It suits mobile, marine and off-grid setups where two different DC voltage systems need to run from one battery bank.\u003c\/p\u003e\u003ch2\u003eKey features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eConversion\u003c\/strong\u003e, 24V input to 12V output at up to 20A continuous, 240W maximum.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIsolation\u003c\/strong\u003e, non-isolated design, sharing a common ground between input and output.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdjustable output\u003c\/strong\u003e, output voltage can be fine-tuned to suit the connected load.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e, 0.26kg, compact enough for tight vehicle, vessel or enclosure spaces.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFootprint\u003c\/strong\u003e, matches other Orion-Tr units, useful when installing several together.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProtection\u003c\/strong\u003e, guarded against short circuit, over-temperature and over-voltage.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eProduct overview\u003c\/h2\u003e\u003cp\u003eThe Orion-Tr range uses a synchronous buck converter topology for efficient DC voltage step-down. Being non-isolated, input and output share a common ground, which is fine for most single-vehicle or single-vessel wiring. Where galvanic isolation is needed, such as separate battery banks on a boat with shore power, the isolated Orion-Tr variant is the correct choice instead.\u003c\/p\u003e\u003cp\u003eAt 240W this unit powers 12V accessories, lighting circuits, control gear or secondary loads from a 24V house or traction battery. The adjustable output lets you compensate for cable voltage drop or match sensitive 12V equipment. No external controller is needed; once wired and set it runs on its own. It shares its form factor with the rest of the Orion-Tr family, so adding units in parallel or moving to a higher-rated model later does not mean redesigning the installation.\u003c\/p\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e12V accessory circuits on a 24V vehicle or truck electrical system.\u003c\/li\u003e\n\u003cli\u003e12V control or lighting loads fed from a 24V off-grid battery bank.\u003c\/li\u003e\n\u003cli\u003eMarine setups where 24V house batteries need to supply 12V navigation or cabin equipment.\u003c\/li\u003e\n\u003cli\u003eMotorhome and campervan conversions running mixed 24V and 12V loads.\u003c\/li\u003e\n\u003cli\u003eTelecom and industrial enclosures needing a stepped-down 12V auxiliary rail.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eInstallation notes\u003c\/h3\u003e\u003cp\u003eInput and output share a common ground on this non-isolated unit, so check this suits your system before fitting, particularly on marine or multi-source DC setups where ground loops can cause problems. Fuse the input wiring close to the source battery to match the cable rating. Output voltage is set via the onboard trimmer. Fitting should be done by an installer familiar with 12\/24V DC systems and mobile or marine wiring standards.\u003c\/p\u003e\u003ch2\u003eWhat's in the box\u003c\/h2\u003e\u003cul\u003e\u003cli\u003e1x Victron Orion-Tr 24\/12-20 (240W) non-isolated DC-DC converter\u003c\/li\u003e\u003c\/ul\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":52061065445664,"sku":"ORI241220200","price":32.01,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1010\/8148\/1504\/files\/ledandsolar-ori241220200-1.webp?v=1785510587","url":"https:\/\/www.ledandsolar.co.uk\/products\/victron-orion-tr-24-12-dc-converter","provider":"LED \u0026 Solar","version":"1.0","type":"link"}
